Downward migration may require codemodification due to fewer available instances of some peripherals. Horizontal migration to the left reduces the pin count and therefore also the available 1-1. tinyAVR 1-Series Overview32KB16KB8KB4KB2KB8142024 PinsFlashATtiny816 ATtiny817 ATtiny814 ATtiny417 ATtiny1616 ATtiny1617 ATtiny414 ATtiny416 ATtiny412 ATtiny214 ATtiny212 ATtiny1614 Devices with different Flash memory size typically also have different SRAM and name of a device of the series contains information as depicted below:Figure 1-2.

Thermal Thermal Resistance DataThe following table summarizes the thermal resistance data depending on the 7-1. Thermal Resistance DataPackage Type JA [ C/W] JC [ C/W]20-pin SOIC300 (SRJ)442120-pin VQFN (ZCL) LinksJunction Junction TemperatureThe average chip-junction temperature, TJ, in C can be obtained from the following:1.

9 TJ = TA + (PD x JA)2. TJ = TA + (PD x ( HEATSINK + JC))where: JA = Package thermal resistance, Junction-to-ambient ( C/W), see Thermal Resistance Data JC = Package thermal resistance, Junction-to-case thermal resistance ( C/W), see ThermalResistance Data HEATSINK = Thermal resistance ( C/W) specification of the external cooling device PD = Device power consumption (W) TA = Ambient temperature ( C)From the first equation, the user can derive the estimated lifetime of the chip and decide if a coolingdevice is necessary or not. If a cooling device is to be fitted on the chip, the second equation should beused to compute the resulting average chip-junction temperature TJ in LinksThermal Resistance Data ATtiny416/816 2017 Microchip Technology Inc.
